Abstract
A CCD frame transfer image sensor wherein the effective integration period can be shortened by electrical means. The sensor comprises an image section having a first photo-sensitive portion of an array of CCD channels and a store section having a second light shielded portion of the array. Means are provided for controlling the potentials applied to the control electrodes of the array so as to transfer along the channels charge generated in the image section into a charge sink structure during one of the active line periods at a frequency outside the bandwidth of the output signal of the sensor.
